and exactly how much would someone spend on roughly 5whp?

 

actually its an intake manifold gasket not a header gasket, not saying it might make a bigger difference but just to correct u

 

img is about 50 bucks and the short ram i think about 200 without installation

oops, my mistake
i was thinking of something else
you are correct sir

 

Just to be real... it won't ever be settled. Soon there will be a stock SI guy claiming to have pummeled a well modded TC. It just goes in circles.

 

1/8mile...

 

Stock wheels, mild traffic

 

why would you move it here.. street racing isn't an auto sport.

lame.

 

that shows a Si going 10.14, when stock I was pulling 9.94... that proves nothing. Could be a bad tC driver. With a passenger in my car I pulled a 10.12.

 

alright guys
my best friend have a new civic si and whenever we go at it he always wins

from a complete stop my car pulls all the way to 2nd gear
then he flys by me with vtec everywhere

and my car is completly stock btw =/

 

lol at vtec everywhere
they are nice cars out of the box
now i don't know if its a k motor thing, but race him again in about 2 months or so
i've owned 2 type-s' and my cousin owns a 07 si and everytime after the car is broken in i would get on it (hard)
it just doesn't feel fast
however, a couple of months down its lifespan
it seems to pick up better
v-tec gets louder
idk, maybe its in my head

 

I guess you're experiencing the only downside of a smaller, high-rev'ing motor...

The fear sets in much later in the powerband... when you start thinking... "wow, i'm really going fast now!"

With a big V8, you could stomp the pedal down at 1500rpm and put the fear of god in your passengers, thats if the tires hook up.

 

i think SO-CAL_TC was trying to say trim level wise, the RSX type-S is pretty much the "high performance" version of a US RSX, likewise for the Civic Si. or how a Toyota Corolla XRS would be the high performance version of a Corolla.

if im not mistaken, the Scion tC has a uni trim, or is the trd s/c the high performance edition?

i like Scion's i was thinking of getting an xA, something small and easy to zip around in a congested city.

 

^^ correct. Scion tC = 1 trim.

S/C'er doesn't count as a trim level.

 

You should get an xA I love mine, and it's a lot peppier than the box, but the xB does have a lot more a/m support.

 

Si's with i\h\e and a hondata reflash puts em at around 200 to the wheels. I don't think the tc wit the same bpu's can match dat with out a tune. Those k series engines are really good all motor. But if they wanna go 300 hp or more on boost or not, the engine needs to be rebuilt. That's where the 2az has an advantage and of course the torque. I've owned 3 civics and one with a fully built b16a all motor. Vtec on full swing is so sweet. Anyways, I just got my tc and only have around 2200 miles on it. Bought it to go boost.

 

Of course

factory 197 hp High compression > factory 160 hp.

but you are correct...approach 300hp on boost and the High Compression motor starts to get sick... Need lower compression for that.

 

hi rhythmnsmoke, i was wondering if you could go into more detail why approaching 300hp on boost on a high compression is bad, if you dont mind me asking. just a bit curious how it all works ^_^

 

I am not that well versed on Compression ratios for motors and what not. But if you read a little, you will get a general understanding that when you want to go ALL-Motor, you will find a piston swap for something like 11:1, 12:1 etc..compression. High Compression is associated with All-Motor setups. Now I did not say you can't Boost a High compression motor. As there are some Si's with F/I on them. The Si motor is like 10:5 or 11:1 (can't remember off the top of my head) compression, where as the tC is 9.6:1. Lower compression allows you to safely turn up and handle more boost onto the motor. Being that we are already decently low compression, we can handle 300whp+ on the stock motor. Would be rather scary to try and do that with a higher compression motor such as the Kseries found in the Civic. Drop in 8:5.1 compression pistons, and you can handle even more boost.

 

thanks for the prompt response sir. i kinda i got he idea, so what youre basically saying is that a higher compression engine is already wound up tightly enough to boost it would be riskier, compared to a less compressed engine. is that right?

 

^^you are getting the gist of it.

Just remember

High Compression = Good for All Motor

Lower Compression = Good for F/I.
